Woody Peony is a kind of precious flower and medicinal tree endemicto China, which has had a cultivation history of over 1500 years. So far,there are over 500 cultivars in China. Most of the research on the classification of woody peony and thedescription and identification of peony species were conducted by scientistsof the western countries on the basis of the peony plants and specimensintroduced into England, USA and France etc. from China during the18th-19th century. In recent years, the author has conducted a series of investigation andstudy on Chinese wild woody peonies in Anhui,Henan, Shanxi, Shaanxi,Gansu, Sichuan and Yunnan Provinces of China. The present paper proposes 3 new species and 1 new status of Chinesewild woody peonies. This achievement leads to provide the scientific andtheoretical basis for the study on the origin and natural classification ofpeony cultivars and exploitation,protection,utilization of Chinese precious,rare and endangered gene resources of wild woody peonies as well as thehybridization of new cultivars and expansion of peony cultivated areaetc. Osti's Peony (Paeonia ostii T. Hong et J. X. Zhang sp. nov.) The species name "ostii" is dedicated to Dr. Gian Lupo Osti, theItalian Vice President of International Dendrology Society. We do appr-eciate his friendly, valuable and precious help to promote the scientificresearch of Chinese wild woody peonies! Osti's Peony differs from Rock's Peony and its congeners are in moreor less lanceolate leaflets with entire margin, glabrous beneath and 4-7pairs of veins, the terminal leaflets 1-3 lobed; petals white or slightlytinged with dilutely reddish color, but without purple basal blotch; fila-ments, disks and styles dark purplish red all together. Jishan Peony (Paeonia jishanensis T. Hong et W. Z. Zhao sp. nov.) It differs from P. suffruticosa Andr. subsp. spontanea (Rehd.) Haw &Lauener in its white flowers and without petaloid stamens. A. Rehder, an American dendrologist, identified and nominated it asa new variety (P. suffruticosa Andr. var. spontanea Rehd.) in 1920, basedon the specimen No, 338 collected by W. Purdom in 1910 at a place loca-ted at 25 kilometers away from the west of Yanan. The original Latindescription of its main characteristics is: "floribus roseis, interdumstaminibus petaloideis praeditis" (flowers roseate, sometimes presence ofpetaloid stamens). In 1990, S. G. Haw & L. A. Lauener changed Rehder's variety intosubspecies (P. suffruticosa subsp. spontanea) and identified the white-flow-ered wild peony which is distributed over Majiagou Jishan County inShanxi Province at the alt. 1450m to the same subspecies. The author thinks that the petaloid stamens is one of the most impo-rtant characteristics of Peony Cultivars originating from wild speciesafter cultivation. It shouldn't be confused with wild peony. Therefore,Haw's subspecies should be lowered and changed to cultivar. The JishanPeony is an undoubted wild woody peony species. Yanan Peony (Paeonia yananensis T. Hong et M. R. Li sp. nov.) It's a rare and endangered wild woody peony species which has asuperficial resemblance to Rock's Peony being dark purplish blotched atthe base of petals, but is easily distinguished by few leaflets (up to 11),smaller and dilutely purplish roseate or white petals,reddish purple stigmaand disk etc. Rock's Peony [Paeonia rockii (Haw & Lauener) T. Hong et J. J. Listat. nov.] It's identified and nominated by S. G. Haw & L. A. Lauener as a new subspecies (P. suffruticosa Andr. subsp. rockii) based on "Rock'sVariety" which was bred from seeds collected by an American Geographer,Joseph Rock in 1925-1926 from a peohy with big white flower and darkpurple basal blotch in a lamasery of Choni County in the south of GansuProvince. The author of Genus Paeonia of Fl. Reip. Pop. Sin. was mistaken toidentify the peony with white flower and dark purple basal blotch whichis distributed over the south of Gansu and Mt. Taibai of Shaanxi Provincesetc. as Paeonia suffruticosa Andr. var. papaveracea (Andr.) Kerner. H. C. Andrews, a British plant taxonomist, studied a

牡丹为我国特产珍贵花树和药用树种,已有1500余年栽培历史,建国以来,各地栽培品种已达500余个。 有关牡丹分类的主要研究成果多为西方科学家根据18—19世纪从我国引种到英、美、法等国的栽培牡丹和腊叶标本加以描述和定名。 作者近几年来在安徽、河南、湖南、山西、陕西、甘肃、四川、云南等地对我国野生牡丹进行了较广泛的调查和研究。 本文发表3个新种和1个新等级,这对研究我国栽培牡丹的起源和栽培品种的自然分类,发掘、保护、利用我国珍稀野生牡丹基因资源,培育新品种,扩大牡丹栽培地区等方面提供了科学理论依据。

The present paper proposes 1 new subspecies and 1 new status or Chinese wild tree peony.Lin's Peony, the new subspecies differs from Paeonia roekii in its lanceolate or narrow ovate and unlobed leanets.Jishan Peony is a very good wild species, from which originating a series of cultivars.So. the author raised Haw's subspecies to species grade, Paeonia spontanea(Rehder) T.Hong et W. F. zhao stat. nov.

本文发表一个新亚种和一个新等级.新亚种林氏牡丹和紫斑牡丹同属一个种系,花瓣基部均具紫斑,花丝、花盘及柱头均为白色;但林氏牡丹的小叶多为披针形或窄卵形,全缘,而紫斑牡丹的小叶多为印形式卵圆形,常1-3深裂。稷山牡丹为我国野生牡丹,其栽培后代演变为若干品种,形成稷山牡丹系列品种群,应定为种的等级.

Ten different oligonucleotide primers of arbitrary sequence were used in Capillary and Air Thermocycler to amplify genomic total DNA of Paeonia suffruticosa subsp. spon-tanea and P. rockii isolated from several local populations in Shanxi, Shaanxi and Gansu provinces. Under the strictly standardized amplification condition for all the primers, these primers yielded clear and reproducible bands corresponding to amplified products and separable by agarose gel electrophoresis.

Ten different oligonucleotide primers of arbitrary sequence were used in Capillary and Air Thermocycler to amplify genomic total DNA of Paeonia suffruticosa subsp. spon-tanea and P. rockii isolated from several local populations in Shanxi, Shaanxi and Gansu provinces. Under the strictly standardized amplification condition for all the primers, these primers yielded clear and reproducible bands corresponding to amplified products and separable by agarose gel electrophoresis. Among a total of 71 bands amplified, 16(22. 5%) were polymorphic in a single individual of P. suffruticosa subsp. spontanea, while among a total of 76 bands 21(27. 6%)were polymophic in a single individual of P. rockii. On an average, the pairwise marker difference between band profiles of conspecific individuals (different populations) was 7. 9 for P. suffruticosa subsp. spontanea and 8. 7 for P. rockii respectively. The average marker difference between P. suffruticosa subsp. spontanea and P. rockii was 10. 3. Obviously, greater number of plants and primers will be required to detect satisfactorily level of genetic diversity. These preliminary results showed that intraspecific genetic diversity was low for the two endangered species. RAPD as a molecular marker was useful and feasible for detecting the genetic variation within species of wild moutans. And it was also potential for studying evolution and relationships between species.

用10个任意序列的寡核苷酸片段作为引物,将采自陕西、山西、甘肃等地矮牡丹与紫斑牡丹基因 组DNA,在毛细管气浴式PCR热循环仪上随机扩增。在对所有引物扩增条件严格标准化的条件下,这些引物可产生清楚的、可重复的与扩增产物相应的琼脂糖凝胶电泳区带。这10个有效扩增的引物在矮牡丹平均每一个体中扩增出71条带,其中多态的带16条(22.5%);在紫斑牡丹平均每一个体中扩增出76条带,其中多态的带21条(27.6%)。对每两个个体,每条多态带进行成对比较,累加后求分子标记差异的平均值。在矮牡丹3个居群间的平均差异是7.9;在紫斑牡丹4个居群间的平均差异是8.7;在矮牡丹与紫斑牡丹2个种间的平均差异是10.3。显然,若用来扩增的植物个体数目和引物数目增加,将会得到更满意的结果。初步结果表明濒危植物矮牡丹与紫斑牡丹种内低水平的DNA多态性。RAPD技术用于检测野生牡丹居群内与居群间的遗传变异是有用的与可行的;用于研究种间的进化和亲缘关系也有潜力。
